The Hot Box is a radiopharmaceutical heating containment system designed to contain airborne radioactive contamination that might result during the routine heating steps 99m required in the preparation of certain technetium Tc labeled radiopharmaceuticals. These radiopharmaceuticals might be, but are not limited to ,any of the following: 99mTc Sulfur Colloid, 99mTc Mertiatide (MAG3 ), 99mTc Sestamibi (Cardiolite or Miraluma), 99m 99m Tc Apcitide (AcuTect ) or Tc Depreotide (Neo Tect )

The Hot Box is designed to house a dry heater. This heater must be smaller than 17 cm high, 23cm wide and 30 cm deep to fit within the Hot Box. This dry heater should be equipped with one or two blocks (as appropriate) and a thermometer. The Hot Box is not designed for use with liquid heating baths that utilize water or other low boiling temperature liquids. The Hot Box is not designed to shield the user from radioactive exposure inherent in the handling of radioactive materials .It is constructed from stainless steel and normal window glass, not lead, tungsten or leaded glass.
